Watch an APR Stage III TT-RS annihilate a tuned Nissan GT-R

The new APR Stage III kit for the TT-RS 2.5 TFSI is a very impressive upgrade. Over 600 wheel horsepower, a Garrett GTX35R turbocharger, and an upgraded HPFP (high pressure fuel pump) combine for a very potent package. Just how potent? Well enough to dispense with a Stage I tuned Nissan GT-R very easily. Yes, there are more highly modified GT-R's out there that can eat this TT-RS up quite easily but the video definitely puts the performance capability of the car in perspective.

Keep in mind this is a 6-speed manual TT-RS. So this is not the transmission doing all the heavy lifting (the driver is a pro driver however) and the GTR of course does benefit from a dual clutch trans.

We haven't seen the fueling on E85 or what the system can handle. How do we know the engine's limit is here? How do we know what the HPFP's limit is?

Going off of what APR said.

We'll need upgraded rods to make more torque most likely. We've hit 40 PSI a few times. Probably not going to last long if we keep doing that on the stock rods.

But again APR doesn't tune for e85 or meth in production. So until someone else comes out with a BT kit or someone takes their APR kit to another tuner to be a guinea pig, you won't be seeing e85 numbers, maybe meth numbers though. MAYBE.

Rods definitely make sense but they still don't say anything about the fuel system limit. Maybe they'll need to upgrade both?

Regardless, I'm sure there is more in it as it sits, more with rods, and then... who knows?
